Abstract

The present application discloses a target tracking method and system. The method includes: performing the first-stage tracking on the target object to obtain N frames of tracking images; extracting and saving the feature map of each frame of the N tracking images and the corresponding feature map coefficients to obtain the corresponding feature pool; use the feature pool to start the second-stage tracking of the target object; wherein, any tracking process in the second-stage tracking includes: calculating the frame tracking image corresponding to this tracking process The responsivity between the frequency-domain feature map and each feature map in the feature pool is obtained to obtain the corresponding N response maps, and then the position with the largest response value in the N response maps is determined as the latest tracking position of the current target object. The present application realizes the optimization of the tracking position of the target object, thereby further improving the target tracking accuracy.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to a target tracking method and system. Background technique [0002] Currently, more and more application scenarios require video image acquisition to obtain relevant video image information in the scene. In some specific cases, it is also necessary to identify and track a specific target in the video image, so as to obtain the location information of the specific target. The existing target tracking technology can generally meet people's basic requirements for target tracking, and its application range is getting wider and wider. It has achieved remarkable results in traffic, criminal investigation, photography, and combating terrorism. [0003] However, the existing target tracking technology still has the problem of low tracking accuracy, and how to further improve the target tracking accuracy is still an unsolved problem. Contents of the invention [0004] In view o...
